The Mission information is (paraphrased) as follows:
- The Away Mission involving hiding behind a mountain-range to survive a nuke has been finished.
- Nexus has just merged with Gamma team.
- You are tasked with destroying them. (I think)

What followed:
- Nothing... (for a minute or so)
- Enemy transport (black) lands in the north-west base. (It was out-of-range, so I don't know if it did anything)
- I assign all indirect weapon units to a sensor unit.
- I focus fire on the transport.
- It slowly loses health as pepper-pots, ripple-rockets, and howitzers rain down on it.
- It reaches 0 health and doesn't die. (at this point I have about 10 minutes left on the mission timer)
- Rinse and repeat previous three actions, but while the transport is at 0 health.
- I get impatient/bored and assign all other units to attack it.
- Nothing happens.
- I attack/destroy the north-east base. (and lose a lot of VTOLs in the process)
- The transport is still not dead, so I fly around the map with a VTOL looking for something I missed.
- Nothing turns up, transport doesn't die, mission timer reaches 0, I lose.

In that case, I will do my best to replicate it AND record it. Are there any other things I should do to help this get fixed?

The bug simply does not exist anymore as almost all of the mission scripts has been redone since the release of 3.2.3. If something like that happens then it would be a completely different cause.

Spoiler:

3.2.x campaign kind of sits in an odd state where there are problems from the original-esqe scripts (largely Gamma campaign and one mission on Beta, for 3.2.3) in conjunction with the new scripts which were unpolished (a lot of times people had problems completing Alpha 1/2/6/7 which used the new JS scripts). Not to say past releases had no problems, cause the certainly did, as the bug you described is 10+ years old itself.

Somehow I found myself continuing NoQ's dream project of jscam (wiki is outdated, but the core goals still apply) slowly over the course of a little over a year. Thorough testing started around August of 2017 with the help of alfred007 and Bethrezen to further push this project into reality (campaign testing thread). I don’t recall all of it, though if you want to read the linked mega thread, then you will see what has been done, discussed, argued, and whatnot for the past few months.

Basically the whole campaign has been worked on with this project.

We try to make the missions as close to 1.10 when possible, however, there are changes to combat exploits (like infinite power gain or completing missions, at times, in less than one minute) or to smooth out game-play, in the case of early Beta research.

There are a few things I still want to do, though I like the state of campaign scripts right now and an uncertain release date makes me not want to do anything major yet.

Saves from 3.2.3 will not work for master or the next release, just as a word of warning. You can play the master builds (http://buildbot.wz2100.net/files/master/windows/ for Windows) if you wish to do any testing or want a better campaign experience in general.

so there's no getting past this level right now, the key is to wait for the next build?

You can either:
1. Use cheat mode by entering "cheat on" into chat (press enter to type) and then typing "let me win".
2. Reload a save before the mission with the problem and try completing the problem mission.
